Summary: Traditional fermentation process had significant effects on pH, titratable acidity, protein, amino acids, and sugar contents of three local sorghum cultivars used in making khamir bread. While pH of fermented dough decreased and total acidity increased, there was no significant change in protein content. Amino acid analysis showed slight variations, and glucose, fructose and maltose content increased initially before decreasing towards the end of fermentation.

Summary: The dynamic variations in key contributing odorants, amino acids, and reducing sugars in shiitake mushrooms during hot-air drying were studied. Gas chromatography-mass spectrometry (GC-MS), high performance liquid chromatography-tandem mass (HPLC-MS/MS) and ion chromatography (IC) were used to determine the variations. The possible precursors of dimethyl trisulfide and lenthionine were explored and methionine (Met), cysteine (Cys), and ribose were considered as potential precursors. Verification experiments confirmed that Met and its interaction with ribose contribute to the formation of dimethyl trisulfide.

Summary: This study aimed to investigate the response of Micro-Tom tomatoes to different fertilization rates and cultivation systems. The results showed that plant growth and yield were significantly influenced by fertilization rate, with the highest yield observed at a rate of 0.52 g L-1. In terms of cultivation systems, hydroponically grown tomatoes tended to accumulate amino acids, while organic and conventional systems showed more accumulation of sugars and organic acids. The yield obtained in the hydroponic systems was more than double that of the soil cultivation methods. These findings are important for promoting organic and hydroponic cultivation of tomatoes.

Summary: Yoghurt fermented under sub-lethal high pressure (10, 20, 30, and 40 MPa at 43 degrees C) and refrigeration (4 degrees C for 23 days) was analyzed and compared with yoghurt fermented at atmospheric pressure (0.1 MPa). Metabolite fingerprinting, sugar and organic acid assessment, and total fatty acid determination were performed. The results showed that certain metabolites varied with increasing pressure, possibly due to the influence of pressure on specific enzymes. Yoghurts fermented at 40 MPa had lower lactose and total fatty acid content. Further research is needed to better understand fermentation processes under sub-lethal high pressure.

Summary: Changes in the chemical environment during the maturation stage play a crucial role in the conversion of somatic embryos to plantlets in Pinus spp. By supplementing maturation media with specific amino acid combinations and carbohydrate sources, improvements in somatic embryo growth, size, and roots development were observed in Pinus radiata and Pinus halepensis. Additionally, differences in polyamine levels, particularly putrescine, were detected between the two species during somatic embryogenesis, indicating species-specific responses to the maturation environment.

Summary: Fatty acid photodecarboxylase of Chlorella variabilis NC64A (CvFAP) is a novel photoenzyme that shows potential in waste lipid treatment and sustainable aviation fuel production. However, CvFAP is susceptible to blue light. In this study, it was found that an anaerobic environment significantly improved the photostability of CvFAP. Decarboxylation of palmitic acid by CvFAP under anaerobic conditions resulted in a 44.7% increase in pentadecane yield compared to aerobic conditions. The residual activity of CvFAP after blue-light preillumination in an anaerobic environment was 80.4%, 258.7 times higher than that in an aerobic environment. The accumulation of superoxide radical and singlet oxygen in CvFAP under aerobic conditions led to its poor photostability. The anaerobic environment helped mitigate the production of these reactive species, thus improving the photostability of CvFAP.

Summary: In this study, CvFAP was immobilized in magnetic nickel ferrite (NiFe2O4) nanoparticles for easy recovery. The interaction between Ni2+ and histidine of CvFAP was clarified by detecting the shift of Ni 2p in electron binding energy. The coordination of NiFe2O4 and CvFAP resulted in an efficient affinity binding with a capacity of 98 mg/g carrier. Hydrocarbon fuel concentration of 3.7 mM was obtained by NiFe2O4@CvFAP-induced photoenzymatic decarboxylation. The high stability of CvFAP in terms of residual enzyme activity of 79.7% at pH 9.0 and that of 68% at organic solvent ratio of 60% was observed.

Summary: Anaerobic digestion (AD) technology is an effective method for biogas production and livestock waste treatment. This study investigated the impact of oxytetracycline (OTC) on the AD process and found that OTC significantly inhibited methane production, with methane yields decreasing by 58.6% and 73.3% in mesophilic and thermophilic ADs respectively at an initial OTC concentration of 400 mg/L. OTC can be degraded by the AD process with a removal efficiency above 90% at lower concentrations. Higher OTC concentrations resulted in lower bio-methane yield, energy conversion efficiency, and contaminant removal in both mesophilic and thermophilic ADs.

Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
